Radio Frequency engineering is one of those fields that humbles even experienced engineers. Once you reach frequencies above a few hundred MHz, the rules change rapidly. Traces stop behaving like wires, impedance becomes a moving target, and your PCB layout quietly decides the fate of your entire design. This article, the first in a multi-part series on “Mastering RF Engineering,” by Mouser Electronics, explores how RF technology is designed, built, and tested, highlighting the principles, compo

Digital RF applications are rapidly growing, driven by advances in digital electronics and increased miniaturization and integration. While some RF systems remain analog due to legacy needs, many modern designs are now almost entirely digital. In these systems, the RF front end (RFFE) is often the only remaining analog component, with digital hardware and software handling tasks like frequency translation and signal conditioning that were once done using discrete RF components or MMICs. This art

Radio frequency tech is everywhere, from the phones in our pockets to the satellites above us. Spanning from mere kilohertz to tens of terahertz, the RF spectrum powers communication, sensing, navigation, and even the unglamorous but essential tools that heat, seal, and sanitize products worldwide. Because RF applications are so diverse, the expertise required is just as broad. Together with Mouser Electronics, we have launched a new series titled “Mastering RF Engineering”. The series examines
